IMPROVEMENT lN SHIRT-BOSOMS.

Specification forming part of Letters Patent No. 120,462, dated October31, 1871.

To all whom it may concern:

Be it known that I, SOLOMON SIBLEY, of Boston, in the county of Suffolkand State of Massachusetts, have invented an Improvement in Shirt-Bosoms, of which the following is a full, clear, and exact description,reference being had to the accompanying drawing making part of thisspecification, in which- Figure 1 is a plan of the back or inner side ofa shirt-bosom made in accordance with my invention. Fig. 2 is atransverse section on the line :v :v of Fig. 1.

In ordinary shirt-bosoms there is but a single thickness of material atthe point where two plaits meet, while the plaits themselves consist ofthree thicknesses, and this thin portion, having a stouter portion oneach side, soon becomes worn out in washing, causing the bosom to crackor split at these points, which renders it worthless, as it cannot berepaired. My invention has for its object to overcome this difficulty,and consists in reinforcing or strengthening a shirtbosom at the pointswhere the plaits meet by the application thereto of strips of linen,cotton, or other suitable material, the additional thickness thus givenat the points where the greatest wear takes rendering the bosom muchmore durable than When made in the usual manner.

To enable others skilled in the art to understand and use my invention,I will proceed to describe the manner in which I have carried it out.

In the said drawing, A represents a shirtbosom, which is folded in theordinary manner so as to form the plaits a b c d e. At the points wherethe plaits meet and where the material is necessarily of a singlethickness only narrow strips f f of linen, cotton, or other suitablematerial are applied, one edge of each strip being secured by the samerow of stitching g, which holds the plait down, the other edge of thestrip being held in place by an extra row of stitching, h. When theshirt is made with an open back, which does not require the bosom toopen in front, the portion i is extended, as seen in Fig. 2, beyond thepoint where the plaits c d meet,

the portion thus extended answering the same purpose as one of thestrips f; but in a bosom which opens at the center the portion z' couldnot be extended and secured in place, and a strip similar to one, j',would then require to be secured in the same manner as the other stripsat the points where the plaitsc d meet. M By thus reinforcingandstrengthening a shirt-bosom by the application of stripsf at the pointswhere the greatest wear occurs it is rendered much more durable, as theliability to crack or split between the plaits is entirely avoided, thethickness of the whole bosom being equalized, so that when starched itwill have no weak places to be acted upon by the stiffer portions, ashas heretofore been the case. Furthermore, it will set more smoothlythan an ordinary bosom, while the expense of the strengthening strips isvery triiiing, as waste pieces of material can be employed which cannotbe used for other purposes.

I am aware that a shirt-bosom has been made with stiffening stripsinserted between the plaits,

Yas described in the United States patent of Ira Perrego, J r., datedSeptembcr25, 1860; but in such bosoms the liability to crack at thepoints between the plaits is increased rather th an diminished, as theadditional thickness is put into the plaits, where it is not required,while the single thickness of material is still left between the twostout portions of the bosom. I, therefore, lay no claim to such methodof making a shirt-bosom 5 but What I do claim as my invention, anddesire to secure by Letters Patent, is-

A shirt-bosom reinforced or strengthened by the application of strips fof linen, cotton, or other suitable material at the points where theplaits meet, substantially as and for the purpose set forth.

Witness my hand this 21st day of September,

SOLOMON SIBLEY.
